AIR-DEFLECTING DEVICE FOR- VTINDOiV-FRAMES.

Application filed April 3, 1920.

To all whom it may concern:

Be it known that I, F RANK W. LANCASTER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Air-Defleeting Devices for "Window-Frames, of which the following is a specification.

One object of my invention is to provide means which can be easily attached to a window frame and which can be moved into various positions to cause air, which would otherwise pass by the window, to be intercepted and deflected into a room so as to supply the room with fresh air and force the foul air therefrom;

Another object is to so construct my invention that it may be easily and quiclzly moved into a position to serve as a water shed to prevent water from entering the window even though the sash is raised and in this manner the sash can remain open while it is raining without possibility of the rain entering the open window.

A further object is to make my invention of a comparatively simple and durable construction.

These objects, and other advantageous ends which will be described hereinafter, 1 attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a front elevation of a window having my invention thereon so placed as to serve as a deflector as above stated,

Fig. 2is a view of similar character to Fig. 1 showing my invention in a position acting as a water shed as above stated,

Fig. 3 is a slightly enlarged elevation, partly in section, showing the device of my invention in the position as shown in Fig. 2,

end of the post 11 is pivoted in a base 13, which is secured to the lower inner surface of the window frame 8; said base having a number of notches 14 spaced apart radially with respect to the pivotal axis of the post 11. The post 11 immediately above the base 13 has an angular portion 15 upon which slidably fits a sleeve 16 so that while the sleeve 16 is free to slide upwardly when lifted, relative rotation between said sleeve and angular portion is prevented. The sleeve 16 has a finger 1? extending radially therefrom and adapted to enter any of the notches 1 1. Thus considering that the base 18 is fixed the post 11 can be locked against rotation in a number of positions as is clearly obvious from the showing in Fig. 6. A deflecting vane 19 which is preferably made of sheet metal has a metallic rod 20 secured thereto either by soldering, brazing or other suitable manner; said rod having an offset portion 21 spaced from the surface 22 of the vane; said rod portion having a screw threaded end 23 which has a thumb nut 21 screwed thereon. The rod portion 21 has a lug 25 which extends to the surface 22 of the vane 19 and a lateral lug 26 which extends in a direction toward the surface 22 but stops short thereof to provide a space 27 between its outer end and the surface 22 as shown in Fig. 3.

The post 11 has a brace arm 28 extending upwardly at an incline; said brace arm at its top being formed in an eyelet 29 through which the portion 21 of the rod 20 extends. The eyelet 29 has two recesses 30 and 81 in its front surface which are in horizontal alinement and when in the position shown in Fig. a with the vane in an upright position the lug 26 fits into the recess 31 and the portion 21 of the rod 20 extends through a slot 32 formed vertically in the post 11; the nut 24 serving to hold the lug 26 within the recess 31 and thereby secure the vane 29 in its upright position. The post 11 can be swung with the vane 19 thus locked to it in the various positions to intercept air passing by the window and thereby cause the air to be deflected into the window. The post 11 is preferably positioned centrally within the width of the window so that the air will be deflected into the window at one side of the post and foul air will be forced out of the window at the opposite side of the post. The slot 32 extends vertically and is formed by furca-tions 33 in the post 11.

l/Vithin the height of the slot 32 the turcations 33 are bent angularly as shown at 3a to provide cavities which taper inwardly as clearly shown in Figs. 1, 3 and a. The rod 20 at the inner end of the ofi-set portion 21 has nubs 35 and 36 projecting therefrom; said nubs extending in directions substan tially at right angles to the directions in which the lugs 25 and 26 extend.

An extension strip 37 has portions 38 which project through slideways 89 on the vane 19. The strip 37 has a notch 40 through which the post 11 projects when the vane is swung into the positions shown in Figs. 2 and 3.

When it is desired to swing the vane from the position shown in Figs. 1 and a to the positions shown in Figs. 2 and 3, the thumb nut 2a is loosened and the vane is pulled outwardly until the lug 26 moves out of the recess 31. The vane is then turned substantially 90 until the lug 26 can he slid through the eyelet 29 so as to permitthe nubs 35 and 36 to position themselves in the recesses 30 and 31 in the eyelet 29. The nut 24 can be hacked to permit the vane to be swung on the nubs 35 and 36 as a pivot until the nut 24: is positioned in the cavity 3% as shown in Fig. 3 after which the nut can be tightened and the vane will be held in a position serving as a water shed to prevent water from entering the window as clearly shown in Fig. 3. The strip 57 can be moved upwardly toward the sash so as to embrace the post 11 and in this manner the device is held firm and in close proximity to the window sash so as to permit air to enter through the window tothe exclusion of rain.

While I have described my invention as taking a particular form, it will be understood that the various parts oi my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set tortlnbut consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended-claims.
